Since its launch, this budget all-foam bed has been discounted to an incredibly affordable price. The initial deal took $200 off all sizes, which then increased to $300 off all sizes.

Siena mattress sales FAQ

What does our Siena Mattress review say?

To conduct our thorough Siena Memory Foam Mattress review, our panel of mattress experts tested the Siena Memory Foam Mattress for a whole month to get an accurate idea of what it's like to sleep on. We found the 10" all-foam bed to be of outstanding value for money (it tops our best cheap mattress guide) and has strong edge support. We were also impressed with its temperature regulation, as it kept our lead mattress tester remarkably cool, especially when considering it's made from memory foam, which can be prone to trapping heat. 

It is also surprisingly firm for an all-foam bed, and we rate as 9 out of 10 for firmness, which contradicts Siena's self-reported 6 out of 10 rating. The firmness means it delivers great support to back sleepers and it's our budget pick for best mattress for stomach sleepers, but it may be far too firm for some. In fact, our side-sleeping testers found it way too hard.

 Are Siena mattresses good for all sleepers?

The Siena Memory Foam Mattress is particularly good for back and stomach sleepers, but side sleepers may find it too firm. The bed's 9 out of 10 firmness rating (firm) means that it provides optimal support to back and stomach sleepers, who need to prevent their hips from sinking so their spine stays healthily aligned. Lightweight and side sleepers, on the other hand, will find this firm bed too hard along the pressure points in the shoulders and hips. 

Do you need a coupon to buy a Siena mattress?

You don't need a Siena Sleep promo code to claim your savings when there's a Siena mattress deal, as all discounts are automatically applied at checkout. Plus, our price comparison technology is constantly pulling in the lowest prices from around the web, so you can be sure you're getting the best Siena deal available.

Can you return a Siena mattress?

Yes, both free shipping and free returns are available when you purchase a Siena mattress. Siena offers a 180-night mattress trial, and a full refund will be given if you're not satisfied with your new bed before the 180-night period is up. This period allows more than enough time to get you through the expert-recommended three weeks.

When is the best time to buy a Siena mattress?

An evergreen $400 off deal at Siena Sleep takes 50% off most sizes, so you don't have to be too strategic about when you buy the Siena Memory Foam Mattress. However, during Sleep Awareness Week in March 2024, we saw Siena take 60% off all sizes of their signature bed, bringing a queen size down to $379 instead of its usual $399 discount price. 

It's also worth waiting to see whether there are further price drops around holiday sales events, such as the upcoming Memorial Day mattress sales in May, the Labor Day mattress sales in September, Black Friday mattress sales and Cyber Monday mattress deals in November, and the Presidents' Day mattress sales in February.
